Terrible Spill at Belmont

Imagine this:

The fatman takes his feet off the pedals
and sits directly on the seat.
He pretends that the staircase down
from the Capitol is the Veledrome.

He pushes off with his weight fully on
the seat, no support from the pedals down
the steps and coasts ever so smoothly
down the steps.

Can anyone name some large blue fruit that come
in pairs...
